AMD Zen 6 Ryzen to “100%” run at above 6.5 GHz – Leaker claims

PC gamers can expect a big clock speed bump from AMD’s Zen 6 Ryzen CPUs

A new leak for AMD’s next-generation Zen 6 Ryzen desktop processors has stated with “100%” certainty that AMD will release desktop CPUs that “clock above 6.5 GHz”. This represents a huge boost in clock speeds over today’s Ryzen 9000 series CPUs, none of which can reach 6 GHz. This report comes from Moore’s Law is Dead

AMD reportedly plans to release Ryzen desktop CPUs with up to 24 Zen 6 CPU cores. These CPUs will use CCDs (Core Complex Dies) with up to 12 cores each. These CCDs have 48MB of L3 cache and can have an extra 96MB of L3 V-Cache added, for a total of 144MB of L3 Cache. AMD will also reportedly use “Bridge dies” to connect their CPU CCDs to a higher-speed IO die, reducing memory latencies.

Zen 6 delayed?

AMD has reportedly taped out its B0 stepping for its Zen 6 silicon. According to Moore’s Law is Dead, AMD has run into an issue with this chip that can impact performance. It is currently unknown how AMD will respond to this issue. Introducing another Zen 6 stepping could delay the launch of its next-generation Ryzen CPU.

AMD has the option to ignore this bug and take a performance hit. Alternatively, it could work around the issue with CPU microcode to limit/lessen its impact. The issue is reportedly minor, but AMD is wary of the competition it faces with Intel’s Nova Lake CPUs. AMD’s launch timing for Zen 6 will be affected by its decision to make or not make a new Zen 6 CPU stepping. This assumes that Moore’s Law is Dead’s reporting is correct and that Zen 6’s B0 stepping indeed has a bug that needs to be addressed.

If these rumours are correct, AMD’s Zen 6 launch will deliver some of the largest improvements that AMD has ever delivered with a new Ryzen generation. With more cores, more per-CCD cache, and higher clock speeds, Zen 6 should deliver much more raw CPU power than its predecessors. Add to that faster die-to-die interconnects with “bridge dies” and Zen 6 core architecture enhancements. If these rumours are true, AMD’s next-gen CPUs should be very performant. That said, it remains to be seen whether these rumours are true. Can AMD deliver desktop CPUs as fast as expected with its Zen 6 designs?
